Tauopathy, neuronal atrophy, and psychological impairments are hallmarks of neurodegenerative diseases, such as Alzheimer's disease, that currently lack efficacious clinical treatments capable of rectifying these issues. To address these unmet needs, we used rational drug design to combine the pharmacophores of DYRK1A inhibitors and isoDMTs to develop psychoplastogenic DYRK1A inhibitors. Using this approach, we discovered a nonhallucinogenic compound capable of promoting cortical neuron growth and suppressing tau hyperphosphorylation while also having the potential to mitigate the biological and psychological symptoms of dementia.

The alternative model for personality disorders (AMPD) has been extensively studied over the past decade, but to date there is no direct comparison of the clinical utility of the AMPD model relative to the Section II personality disorder (PD) model in an ecologically valid design. The current study examined the clinical utility of an AMPD-informed assessment procedure and Section II PD assessment procedure as assessed by both patients and clinicians in a randomized controlled trial. A sample of 119 patients were randomly assigned to either an AMPD or a Section II PD assessment procedure.

Article Synopsis
  • Decreased dendritic spine density in the brain is linked to mental health issues, and psychedelics might help brain cells grow stronger.
  • Scientists found that a special receptor in the brain, called 5-HT2AR, is really important for how psychedelics change brain connections, but not all drugs that affect this receptor work the same way.
  • They discovered that the 5-HT2ARs inside brain cells might be the key to these changes, suggesting new ways to treat brain problems and hinting that serotonin might not be the usual signal for these receptors.

Psychedelic compounds have displayed antidepressant potential in both humans and rodents. Despite their promise, psychedelics can induce undesired effects that pose safety concerns and limit their clinical scalability. The rational development of optimized psychedelic-related medicines will require a full mechanistic understanding of how these molecules produce therapeutic effects.

Psychedelics are increasingly being recognized for their potential to treat a wide range of brain disorders including depression, post-traumatic stress disorder (PTSD), and substance use disorder. Their broad therapeutic potential might result from an ability to rescue cortical atrophy common to many neuropsychiatric and neurodegenerative diseases by impacting neurotrophic factor gene expression, activating neuronal growth and survival mechanisms, and modulating the immune system. While the therapeutic potential of psychedelics has not yet been extended to neurodegenerative disorders, we provide evidence suggesting that approaches based on psychedelic science might prove useful for treating these diseases.

The auxin-inducible degron (AID) system has emerged as a powerful tool to conditionally deplete proteins in a range of organisms and cell types. Here, we describe a toolkit to augment the use of the AID system in Caenorhabditis elegans. We have generated a set of single-copy, tissue-specific (germline, intestine, neuron, muscle, pharynx, hypodermis, seam cell, anchor cell) and pan-somatic TIR1-expressing strains carrying a co-expressed blue fluorescent reporter to enable use of both red and green channels in experiments.

In sexually reproducing metazoans, spermatogenesis is the process by which uncommitted germ cells give rise to haploid sperm. Work in model systems has revealed mechanisms controlling commitment to the sperm fate, but how this fate is subsequently executed remains less clear. While studying the well-established role of the conserved nuclear hormone receptor transcription factor, NHR-23/NR1F1, in regulating molting, we discovered that NHR-23/NR1F1 is also constitutively expressed in developing primary spermatocytes and is a critical regulator of spermatogenesis.

Background: Pancreatic cancer is a devastating disease with a 5-year survival rate of 20-25%. As approximately only 20% of patients diagnosed with pancreatic cancer are initially staged as resectable, it is necessary to evaluate new therapeutic approaches. Hence, neoadjuvant (radio)chemotherapy is a promising therapeutic option, especially in patients with a borderline resectable tumor.

Background: Resection of the para-aortic lymph node (PALN) group Ln16b1 during pancreatoduodenectomy remains controversial because PALN metastases are associated with a worse prognosis in pancreatic cancer patients. The present study aimed to analyze the impact of PALN metastases on outcome after non-pancreatic periampullary cancer resection.

Methods: One hundred sixty-four patients with non-pancreatic periampullary cancer who underwent curative pancreatoduodenectomy or total pancreatectomy between 2005 and 2016 were retrospectively investigated.

Ampullary cancer represents approximately 6% of the malignant periampullary tumors. An early occurrence of symptoms leads to a 5-year survival rate after curative surgery of 30 to 67%. In addition to the tumor stage, the immunohistological subtypes appear to be important for postoperative prognosis.

Objective: We aimed to determine the impact of surgical experience and frequency of practice on perioperative morbidity and mortality in pancreatic surgery.

Methods: 1281 patients that underwent pancreatic resections from 1993 to 2013 were retrospectively analyzed using logistic regression models. All cases were stratified according to the surgeon's level of experience, which was based on the number of previously performed pancreatic resections and the extent of received supervision (novice: n <  20 / intensive; intermediate: n = 21-90 / decreasing; and experienced surgeon: n > 90 / none).

Accumulating evidence documents the efficacy of Therapeutic Assessment (TA) in terms of symptom reduction and other outcomes, but only minimal data speak to the patient's perspective of what is memorable, or potentially important, about this intervention. In line with the humanistic and phenomenological philosophy of TA, we solicited patient input by asking personality disorder (PD) patients who participated in a recent randomized controlled trial (De Saeger et al., 2014 ) about their experiences.

The field of clinical personality assessment is lacking in published empirical evidence regarding its treatment and clinical utility. This article reports on a randomized controlled clinical trial (N = 74) allocating patients awaiting treatment in a specialized clinic for personality disorders to either 4 sessions of (a) therapeutic assessment (TA) or (b) a structured goal-focused pretreatment intervention (GFPTI). In terms of short-term outcome, TA demonstrated superior ability to raise outcome expectancies and patient perceptions of progress toward treatment (Cohen's d = 0.
